Products of the plastic industry
The plastics industry processes polymers in a wide variety of forms - from base polymers to compounds to highly functional masterbatches. Whether polyethylene, polypropylene, engineering plastics, or specialty polymers: the properties of the end product are significantly determined by the composition and quality of the premix.
In practice, plastic products rarely originate from a single raw material. Dyes, stabilizers, flame retardants, fillers, or fibers are deliberately combined to adjust mechanical, thermal, or optical properties. It is precisely here that precise, reproducible mixing technology determines process stability, product quality, and cost-effectiveness.
Typical products and terms in plastic processing:
- Polymers and polymer blends
- Compounds and masterbatches
- Additives, stabilizers, and pigments
- Flame retardants and functional additives
- Glass fiber, mineral, and filler mixtures
- Powder mixtures for technical plastics
Requirements when mixing polymeric systems
Mixing plastics places special demands on process technology. Polymers, additives, and fillers differ greatly in particle size, density, and flow behavior. The goal is to distribute all components evenly without damaging the particle structure or risking segregation. Many additives are used in very small quantities but must still be distributed evenly throughout the entire mixture. At the same time, polymer-based systems are sensitive to mechanical overloading: excessive shear forces can destroy particles, generate dust, or negatively affect flow properties. In addition, the processing of abrasive fillers such as glass fibers or mineral aggregates poses high demands on the service life of mixing tools and the protection of product-contact surfaces. Therefore, mixers that operate gently, enable short mixing times, and are robustly designed are in demand.
amixon® solutions for the plastics industry
amixon® develops and builds mixing technology for plastic applications, focusing on homogeneous polymer blends, short mixing times, and gentle product handling. The systems are designed for dry powder and granulate processes and can be flexibly adapted to different formulations and batch sizes.
Wear-resistant versions are available for abrasive plastic formulations. Wear-resistant materials, coatings, or interchangeable protective elements reduce abrasion and ensure long service life – even when processing glass fibers or mineral fillers.
Typical process applications in the plastics industry:
- Mixing of polymers, additives, and colorants
- Production of compounds and masterbatches
- Incorporation of glass fibers, minerals, and fillers
- Homogeneous distribution of additives with short mixing times
- Residue-free discharge for quick product changes
amixon® Mixing Technologies in Focus
The SpherHelics® Hollow spherical mixer Type SH is the entry into the world of amixon® precision mixers. It is designed for a simple, uniform product movement. It is particularly suitable for polymer-based mixtures where sensitive additives should be gently distributed and stable flow properties maintained.
The Gyraton® mixer is a precision silo mixer for large batches of 10 to 100 m³. The slow, controlled product movement ensures high mixing quality with low energy consumption, high residual discharge rates, and a compact design.
The Vertical single-shaft mixer / ribbon blender (VM) offers intensive but controlled mixing. It is used when polymer powders, additives, and fillers need to be reliably homogenized - even with different bulk densities and particle sizes. At the same time, it is paired with a very compact design for easier integration into existing systems.
Technical center and process development
In the amixon® technical center, plastic formulations can be tested with original materials. Mixing quality, energy input, discharge, and cleanability can be evaluated in a practical manner and designed specifically for industrial use.
Plastic products are created from the interaction of many components. A mixing technique that combines polymers, additives, and fillers evenly, gently, and reproducibly is the basis for this. amixon® develops and builds this mixing technology. Speak to us about your polymer and plastic processes.
